Let's say I have something like this:

struct Foo {
    int[] bar;
    this() {
        bar.length = 10;
    }
    ref int opIndex(size_t i) {
        return bar[i];
    }
}
void main() {
    Foo f = Foo();
    f[3] = 15;
}

If I wanted to check whether the assigned value is within a range, and I want to throw a certain exception if outside of it, then how I can do that?

You can't with ref, you will need to do separate getter and setter properties for that.
